Speeding up a Chart

I have a chart with 8 TeeLine Series, each TeeLine with near of 86400 values (temperature/second). But with this amount of data, the chart becomes very slow to response. Zoom is impossible with this amount of data.
So, I need some tips to improve the chart performance.

Hello,
Hiding as many visual effects as possible may improve the performance a bit. Ie:
Code: Select all
Chart1.title.visible=false;
Chart1.legend.hover.enabled=false;
Chart1.legend.format.shadow.visible=false;
Chart1.panel.transparent=true;
Chart1.walls.back.visible=false;
Chart1.panel.format.gradient.visible=false;
Chart1.panel.format.shadow.visible=false;
Chart1.axes.left.grid.visible=false;
Chart1.axes.bottom.grid.visible=false;
for(var t=0; t<Chart1.series.items.length; t++) {
series = Chart1.series.items[t];
series.format.shadow.visible=false;
series.hover.enabled=false;
}
I've added two requests to the public tracking system asking the
DrawAllPoints feature already present in the other versions, and asking for
a faster option to draw the zoom rectangle.

I did some of them. I'll try your suggestion.
